Below are photographs of two Brilliant Uncirculated Jefferson nickels. Note that these are variations of dies used to mint the 1970-D Jefferson nickels. The die variation is clearly evident with the placement of the D in two different locations, one closest to the 1970 and the other closest to the rim of the coin. [1]
Key dates for the series include the 1939-D, and 1950-D nickels. The 1939-D nickel with a mintage of 3,514,000 coins is the second lowest behind the 1950-D nickel. The cause of the key date of 1939 stems from the new design that excited collectors the year prior, after the initial hype had settled down fewer nickels were saved.
The outer coin makes two rotations rolling once around the inner coin. The path of a single point on the edge of the moving coin is a cardioid.. The coin rotation paradox is the counter-intuitive math problem that, when one coin is rolled around the rim of another coin of equal size, the moving coin completes not one but two full rotations after going all the way around the stationary coin ...

Nickel-62 is an isotope of nickel having 28 protons and 34 neutrons. It is a stable isotope , with the highest binding energy per nucleon of any known nuclide (8.7945 MeV). [ 1 ] [ 2 ] It is often stated that 56 Fe is the "most stable nucleus", but only because 56 Fe has the lowest mass per nucleon (not binding energy per nucleon) of all nuclides.
The 2006 and 2007 coins only have been issued in a one-ounce version, but in 2008, $5, $10, and $25 face value coins were minted with 1/10 oz, 1/4 oz, and 1/2 oz of gold respectively. After a long wait by both collectors and investors, the uncirculated version of the American Buffalo gold piece was made available to coin dealers on June 20, 2006.
